WebApr 7, 2024 · In gluconeogenesis, the following new steps bypass these virtually irreversible reactions of glycolysis: 1. Phosphoenolpyruvate is formed from pyruvate by way of oxaloacetate through the action of pyruvate carboxylase and phosphoenolpyruvate carboxykinase. 2. Fructose 6-phosphate is formed from fructose 1,6-bisphosphate by … Web获取原文并翻译 ... Several mucus-related gene families expanded early in the Stylommatophora lineage, and the haemocyanin and phosphoenolpyruvate carboxykinase families doubled during WGD, and zinc metalloproteinase genes were highly tandemly duplicated after WGD. This evidence suggests that although WGD may not have been the …
